Emirates agreed to order 20 Airbus A380 airliners along with an option for 16 additional superjumbos in January. Now, the $16 billion deal is reportedly in danger of falling apart according to Bloomberg.

Airbus and Boeing each own roughly 50% of the global airliner market. The rivalry between the US and the European titans started more than 40 years ago when Airbus launched its first plane called the A300.

Qantas Flight 94, an Airbus A380, took a 10-second "nosedive" over the Pacific Ocean on Sunday, passengers said, as it flew through the wake turbulence caused by another Qantas Airbus A380 flying 1,000 feet above.
